Mercury 3F2Z-9G756-AC Fuel Injector Pressure Sensor

You can Select Your Vehicle to check if 3F2Z-9G756-AC fits your vehicle.

To relieve the fuel pressure, disconnect the cable from the negative battery terminal. Lift the engine cover up and off of the ballstuds, then remove the cover. Disconnect the FPS sensor electrical connector. Unscrew and remove the sensor from the supply line. For installation, lubricate the O-ring with engine oil and tighten the sensor.

An FRPT sensor is fitted on the left fuel rail and the only difference between the 4.6L V8 and the 4.0L V6 engine is that of size. First of all turn off the fuel supply at the fuel pump and unbend the cable from the negative terminal of the battery. Next remove the fuel pump, to do this relieve the fuel system pressure, and depress the release tab and further disarm the electrical connector of the FRPT sensor, again, disconnect the vacu, and unbolt the mounting bolts of the sensor. After that, unbolt the old O-ring from the FRPT sensor and free from any contamination and debris the joining surfaces of the sensor and the fuel rail. Place a new O-ring onto the FRPT sensor and vice versa process of removal and finally, tighten the mounting bolts to the recommended torque. Last of all power on the car and look into the area around the FRPT sensor for any sign of fuel leakage.

The Evaporative Emissions Control (EVAP) system is the system that is used to reduce the chance for fuel system emissions to evaporate and release unburned hydrocarbons into the atmosphere. During hot days, fumes in the fuel tank expand and when there is pressure build up, them is passed through the fuel vapor vent valve and the fuel vapor control valve to the EVAP canister where it is stored for some time until the engine can use it. The many elements of this system are installed underneath the vehicle; these are EVAP canister which is packed with activated charcoal, the check valve, dust separator and the canister vent solenoid. The fuel tank pressure sensor measures pressure inside the tank, and sends data to the PCM during leak tests. The fuel vapor vent valve regulates vapors that are to be admitted into the EVAP system while the fuel vapor control valve shuts off liquid fuel from entering the canister during fuelling. The canister vent solenoid is open most of the time and tests to seal the system and the EVAP check valve vents the air during refueling. The canister purge valve managed by the PCM controls the flow of the vapor into the intake manifold and its working is dependent on the manifold vacuum and the sensor. Some of the typical signs that indicate a defective-evaporative emission control system include foul smell of fuel, rough idle, and stalling, and in most cases, the hose connections and some of the components associated with the system are often checked for damages or leakage. To ensure that there is no increased fuel vapor pressure then the gas cap should be disconnected so that pressure can be heard to be escaping. Component replacement entails a step of disconnecting the battery and when replacing particular components, there is need to remove them and replace them with the right part and reconnection of the PCM for better performance.

To replace the FTP sensor, raise the vehicle and support it securely on jackstands. Disconnect the vapor tube from the quick disconnect fittings and remove the vapor tube and FTP sensor. Installation is the reverse of removal.

Remove the fuel rail from the front cylinder head.

Yes, this sensor is compatible with a Ford Taurus

This is located on the top of the engine on the fuel rail
